libHaru is a free, open-source ANSI C library for generating PDF files, supporting text, lines, images, annotations, font embedding, compression, and encryption. It is generation-only and does not read or edit existing PDFs.
Use cases
- generate pdf files from c or c++
- create pdf reports programmatically
- embed png and jpeg images in pdfs
- create encrypted pdf documents
- generate pdfs with cjk fonts
- produce pdf invoices from an application
When to choose
- you need to create PDFs from C/C++ or via language bindings
- you need a lightweight, cross-platform PDF generation library with no PDF-reading needs
- you need encryption, CJK fonts, or PDF/A support in generated documents
When to avoid
- you need to read, parse, or edit existing PDF files
- you need an actively developed project with fast bug fixes
- you want a high-level document layout engine rather than a low-level drawing API
